Abstract Orthogonal controllable reactors (OCRs) have the advantages of low harmonics and linear inductance regulation, which have wide application prospects in the field of power quality control. However, the traditional OCR has small inductance regulation range and large space occupation. Therefore, two compact reactors, namely type-I and type-II, are proposed in this paper. Firstly, the magnetic circuit models of the reactors were analyzed. Secondly, the simulation models were established and the inductance regulation characteristics of the two OCRs were obtained. Lastly, two 220V prototypes were developed, and an experimental platform was built to test the inductance regulation characteristics. The results show that, compared with the traditional one, the space occupation of the type-I topology is reduced by 53.7%, and the inductance regulation range is doubled. The type-II topology increases the inductance regulation range by 1.93 times. In addition, the orthogonal topology realizes the decoupling of control and working windings.
